Items of a GameObjectItemsSetter are initialized with one frame delay

"It looks like LateUpdate is an issue for me. I have a collection and GameObjectItemsSetter which instantieate gameobject with internal contextHolder. The problem is that Frame1 - Read collection instantiate object instances (with default values in text fields, images, etc) Frame2 - TextSetters, ImageSetters change value to actual value from contexts"

Added a global initializer for the data context node connectors. It makes sure that initializations that are scheduled by previous initializations (e.g. GameObjectItemsSetter) are executed within the same frame without any delay.
